Versatile Size Reduction for Laboratory Sample Preparation
The HM 1-L Hammer-/Cutting Mill is designed for the efficient preparation of large quantities of soft to medium-hard materials with a Mohs hardness of approximately 2–5. Its interchangeable rotor system allows the unit to operate as either a hammer mill or a cutting mill, providing flexibility for a wide range of laboratory applications.

The hammer mill configuration uses impact forces for size reduction, while the cutting mill configuration uses shear forces. This dual-function design enables laboratories to process different material types using a single system.
